An Improved Time Integration Algorithm: A Collocation Time Finite Element Approach Academic Article uri icon

abstract

  • © 2017 World Scientific Publishing Company. A time collocation finite element approach is employed to develop one- and two-step time integration schemes with algorithmic dissipation control capability. The newly developed time integration schemes are combined to obtain a new family of time integration algorithms using the concept employed by Baig and Bathe. The newly developed algorithm can effectively control the algorithmic dissipation by relating the collocation parameters with the spectral radius in the high frequency limit. The new algorithm provides better accuracy compared with the generalized-α method for highly dissipative cases and includes the Baig and Bathe method within its family as a special case.
